Double glazed sealed replacement units provide significant savings, increasing your home's energy efficiency and keeping you safe from the elements. It's an investment worth making.

Installing a new sealed unit requires careful preparation. To avoid breaking or strain the glass slowly and steadily. Then, you should carefully reinstall the unit to make sure the frame is secure.

Remove the Old Unit

Over time double glazed windows or sealed units as they are often known, can fail. A common sign of this is the appearance of fog between the two glass panes as condensation forms inside the cavity of the unit. This is a signal that it is time to replace the unit.

Replacement units are a cost effective way to reduce heating costs and improve the efficiency of your home's energy usage. The space between the two glass panes decreases heat transfer and lowers your power bills. It also helps to keep your home warmer in winter and cool in summer. double glazing window seal repair can also help reduce the noise outside, resulting in an unwinding and relaxing home environment.

The first step to replace a double glazed window is to remove the old sealed unit. It may seem difficult, but with the right tools it isn't. It is essential to have a second pair of hands since the machine is hefty and can be dangerous when handled improperly. It is best to take out the retaining beads that surround the frame in a systematic and safe way.

After all the retaining beads is removed, the unit can be lifted from its frame. The best way to do this is over a soft surface like carpet to avoid any damage to the frame or glass. Lift the unit slowly and gradually to avoid any stress or damage.

With the old unit gone and the frame ready for the new one to be put in, it is now necessary to accurately take measurements of the width, height and thickness of the unit to be replaced. This is essential since the UPVC frames that the which the sealed unit is placed in have very little tolerance and if the new unit is too large, it will not fit.

The next step is to remove the glazing tape from the frame's edges and the putty to prepare it for installation of the new unit. It is important to use a premium silicone sealant as it will create a water tight and durable seal around the edges of the frame that will last for many years to come.

Installing the New Unit

Double glazed windows typically have two glass panes, with a spacer bar that creates an insulating gas or air-filled gap between them. The spacer bar could be made of Low-E (Low-Eissance) glass or desiccants that reduce the infiltration of moisture. The window designer will take precise measures to ensure that the sealed unit is perfectly fitted into the frame. The accuracy of measurements is crucial to ensure that the replacement is energy efficient and provides homeowners the most efficient results.

The next step is to prepare your frame for the installation. To prepare the frame for sealing, first make sure it is free of rust and paint. Clean the frame thoroughly to ensure a smooth surface. The frame should be properly aligned to ensure that the glass is placed properly and won't suffer from warping or misalignment as time passes.

After completing the preparation steps and preparing the unit, it's time to install the newly sealed unit. This delicate procedure requires patience and precision. Carefully guide the new piece into the frame, ensuring that it is absolutely square within the frame. If you are having trouble you could ask a friend to assist you by holding the glass as you place the beads back.

It is a good plan to remove the beads and measure them prior to when you begin so that the new unit is the correct size. To do this, pull out the "beads" by using a sharp chisel or wide-blade screwdriver. Work slowly to ensure that you don't damage the frame or surrounding structure.

Once the new sealed unit is installed then apply a thin layer of liquid for washing to the rubber strip on the bead to help it glide into position and ensure that you don't damage the frame or the unit by putting too much stress on it. If you have a window design that utilizes brickmould, it is the first thing to do to protect it from rotting or moisture infiltration.

Verifying Your Work

Modern replacement double glazed units (also called IGUs) consist of two or more glass panes, separated by a spacer bar that creates an insulating gas or air gap. Spacer bars typically include a solar-control coating that controls the circulation of UV light that enters the home, and assists with insulation. They are designed to keep your home cool during summer and warmer during winter. This reduces the amount of energy that your fans and heaters require which is healthier for the environment.

It's time to replace your sealed unit if it has failed. The units that fail allow air to enter your home, reducing the efficiency of cooling and heating. It can also cause moisture to leak between the window panes, leading to a build-up of condensation and mould.


The presence of moisture between windows is a sure sign that the window needs to be replaced because it is no longer performing its intended function of keeping cold air out and warm energy from your heating in. The misting can also make the window appear unattractive.

After cleaning, a quick inspection of the frame will reveal any damage that needs repair. This is especially crucial for wooden frames, which are prone to deterioration under Australia's harsh climate. Wood filler and sanding can be used to repair minor damages however professional repair is required for the most serious damage.

Once you've finished the repair, it's crucial to choose a top-quality sealant that is able to stand up to thermal expansion and contraction without becoming brittle or deteriorating. Apply the sealant evenly across the frame's perimeter. Smooth it to give it an elegant, smooth finish.

The final step is to secure the unit within the frame. Insert the retaining beads, and secure them using the wedge gasket. This final step is more than an officiality. It is your responsibility to ensure that you have increased the comfort and safety of your family home. After the windows have been installed, they will be ready to withstand the various weather conditions in Australia and provide warmth and cooling during winter and summer.

IG (insulated-glass) sealed units are often referred to as double-glazed windows. They are composed of two panes, one transparent and the other Low-E separated by a spacer bar, which is filled with insulating gas or air. Desiccants could be included too. Some of the insulating glass units are also gas filled that allows them to attain higher Window Energy Ratings.

Over time, double-glazed units or sealed units, as they are more commonly called, can fail. This may be due to the method in which they were originally constructed or the use of abrasive cleaning products that can damage seals. In some instances the thermal insulation properties of the glass may become compromised and result in a loss of effectiveness.

The most frequent issue is the air tight seal between the glass. This is due to gradual degradation over time. Temperature fluctuations cause the glass to expand and contract, causing the seals to weaken and looser. This could lead to an air leak between the panes in some cases.

To prevent this from happening avoid this, it's recommended to replace the sealing beads with premium silicone or another similar product. It's easy to do this by removing the beads using a chisel.

It is also important that the glazed unit be placed in a square frame. This can be done by measuring at different points along the frame.
